How to use pesticides in rainy weather
1. Selecting quick-acting pesticides: pesticides with fast insecticidal effect and good effects can be used to kill pests within 1-2 hours after application, thereby reducing the impact of rain on efficacy. 2. Selecting systemic pesticides: Some systemic pesticides can be absorbed into the plants within a short time after spraying, and can also prevent and control pests during rainfall. 3. Choose rain-tolerant pesticides: Some pesticides are more resistant to rain erosion, and falling showers about 2 hours after spraying basically do not affect the effect of pest control. 4. Adding adhesives to pesticides: The proper amount of adhesives added in the formulated liquid can increase the adhesion of pesticides on plants and the surface of the pests and insects, and can significantly reduce the leaching of liquid chemicals in the event of rainfall. 5, make full use of the rain gap spraying pesticides: In the intermittent period of precipitation, spraying in time, but avoid spraying the edge of the rain. 6. Improve the method of spraying: When it is rainy, choose a systemic pesticide that should be mixed with fine soil before the occurrence of pests, and apply it to the shallow layer on the ridge. After the plant absorbs it, it will be transmitted to the whole plant, which will cause pests to bite and poison and die. This method can avoid rain erosion, prevent the loss of efficacy, and increase the insecticidal effect. In addition, the concentration of the application can also be appropriately increased.
